This is an activity about the detection of magnetic storms. Learners will plot the locations of magnetic observatories in Canada and analyze the magnetic intensity for each station, looking for the difference between stable magnetic activity and the...(View More) largest difference in change in magnetic activity and identifying any patterns of change. This is the thirteenth activity in the Exploring the Earth's Magnetic Field: An IMAGE Satellite Guide to the Magnetosphere educators guide.(View Less)

This is an activity about observation. Learners will make a 3-dimensional model of a mock planetary surface inside a box, and then place a lid on top. They will then introduce a simple probe, such as a pencil or stick, at various points through...(View More) regularly-placed holes in the box top to touch the surface below. Then, they will record the depth at which the probe descends, using the data to make a contour map of its surface. This will help learners see how scientists can research objects which are not easily studied strictly by visual means. This is Activity C-7 of Universe at Your Fingertips 2.0: A Collection of Activities and Resources for Teaching Astronomy DVD-ROM, which is available for purchase.(View Less)

This is an activity about size and scale. Learners will identify and label their location on a series of maps, at successively larger scales, starting with their classroom location outward to the Milky Way galaxy.

This is an activity about shape. Learners will investigate that the Earth is a sphere by comparing the length of shadows from nails arranged on a flat map compared to nails arranged around a spherical globe. From the observations collected, they...(View More) will infer that different shadow lengths at different locations would clearly indicate that our planet is not flat.
